Hi.
I've only had my mate 10 Pro for 2 weeks now and I'm still trying to work out the whole notification issue!
My biggest concern was that I wasn't getting reminders through from a task app that I use a lot. I had to switch to a different task app and make some app permission changes and now these come through.
I seem to get most notifications through at the moment, I'm not sure if that had anything to do with a recent software update or not, so overall I'm happy. To be honest though I couldn't guarantee you that I'm getting all notifications through, and to be honest it doesn't bother me that much for how I use my phone.
I'm sure the other guys who've had there phones longer will be able to give you a better answer than me!
Overall though this is a great phone and for the price I got it for I'm very happy with it.
I'm still trying out the camera and have some small concerns about low light pictures but other than that it's quick, lag free, has an amazing battery, has a great screen (albeit only fhd), camera overall seems very good so far and charges quickly.
It's slippery though so you'll need a case!
